Pyramid Defense: Laser TD

Every sealed room can strengthen your defense or open a new Rift.

Pyramid Defense is a tactical tower defense game built around exploration, routing, and risk. Activate connected rooms, discover Laser and Seal Modules, then shape the enemy path before each incursion reaches the Ascension Room.

Plan the circuit

Activate a stable circuit, then decide whether to stop or push into volatile rooms. Extra expansion can improve your defense, but the chance of opening another Rift keeps rising.

Build the route

Deploy Laser Modules to destroy corrupted creatures. Place and reinforce Seal Modules to block rooms, redirect enemies, and strengthen key defensive positions.

Master the laser grid

Upgrade Lasers and improve their calibration through combat. Mastered Laser Rooms link together into force barriers that damage enemies crossing the network.

Descend deeper

Each floor expands the pyramid. Later cycles bring faster waves, stronger enemies, and elite threats.

Recent changes:
Mastered Laser Rooms now work together! When at least two Lasers earn ★ mastery, they automatically form a force-barrier network. Monsters crossing a barrier take damage from the combined power of every ★ Laser, with repeat hits while contact continues. Includes new barrier visuals, impact effects, and sound.
